CASK AND THE LIKE.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed February 18, 1909. Serial No. 478,725.

To all whom it may cmicern:

Be it known that I, W lLLL-XM IlOULKEK, a sulnect of the King of GreatBritain, residing at Nelson, in the Dominion of New Zealaud,

have invented a new and useful Improvement in or Relating to Casks andthe Like; 1

zigzag.

and I do hereby declare the following to be.

a full, clear, and exact description of the l either ol the ways shownin the drawings, by

same.

This invention has been designed in order to provide for the coopcringoi cylindrical l casks and other like articles, such as vats or tubs, inan e'll'ective and quick manner.

At present it is the custom to cmistrlu-t tractcd or expanded, asrequired.

casks and other like articles with tapering 1 sides, in order to providefor the hoops being ]:t]Y\Hl6(l tlghtly around them, and this man 3 nerol' constructmn entails a considerable Waste of material in shaping thestaves, and

a good deal of trouble in assembling and bending them into position.Moreover, by reason of this tapered shape, the cask re.- quires moreroom for storage than it made truly cylindrical.

Hitherto, a satisfactory manner of eocpcring casks made in a cylindricalform has not been discovered by reason of the absence of any taper onwhich to j am the hoops. With this invention, such will be possible, andit Will, therefore, allow for the casks being made cylindrical, and thusobviate the Waste and tronlole before mentioned.

The invention consists in providing a ring adapted to he placed. betweenthe cask periphery, and each hoop. This ring is formed with a taperextending from one edge to the other, so that when the hoop is placed011 the thin edge, and driven down over the thickened part, it willcause such ring to close in around the cash stave-s, and hold themtightly together in the usual way. in order that the ring may be able togive in with the varying diameters it will have to assume, it is formedpreferably of a strip of metal bent into a sinuous, zigzag or other 22of Fig. 1. Fig. 3 is a view of an upper end of a cash, showing themanner of applying the invention, the ring and hoop being cna 'geratedin size relatively to the cask. rigs. 4. and 5 are respectively sideelevation.

and cross section of portion of a ring formed A, is the ring that ispreferably formed in means of a strip ol suitable metal bent longitudinally into sinuous or zigzag term, and thus to provide for itsdiameter being eon- The ring may, however, l-e formed in any otherapproved way that will provide for this property. it is so shaped thatit will form a taper from one edge to the. other, as shown in Figs. 2and. of the drawings.

in. use, the ring will to placed around the staves of the cask B (Fig.3) and the hoop (3 then placed around the ring and driven down from thethinner edge of the ring on to the thicker part, thus causing the ringto tighten around the staves, and to draw their edges together in theusual way, while the hoop and ring become amined together upon the cask.

What l do claim as my invention, and desire to secure by Letters Patent,is,

in casks and the like, the combination with each of the encirclinghoops, of a ring ol' metal contractiblc and expansihle in diapprovedform that will provide for it being is a cross section thereof, taken onthe line ainetcr, and of tapered thickness transversely across its widthplaced between the cask, and such encircling hoop, substantially asspecified.

'3. in casks and the like, the combination with each of the encirclinghoops, ol a ring composed ol a strip of metal bent longitudinail intosinuous or crimped or zigzag form and of tapered thickness across thewidth ol the ring, piaced between the cask and such. encircling hoop,substantially as specified.

in testimony whereof, I have signed this specification in the presenceoi two sub scribing witnesses.
